The study examined the mortality rates of 670 adults with acute severe hypertension over short (hospital) and long-term (12 months).
About 57.5% of patients experienced hypertensive emergencies, with hospital mortality at 7.9% and significantly higher for emergencies (12.5%) compared to urgencies (1.8%).
After 12 months, 29.4% of patients had died, predominantly due to hypertensive emergencies, indicating a need for improved follow-up and treatment strategies for these patients.
